The CRBT service is a telecom value-added service customized by the called customer to provide the calling customer with a piece of pleasant music or a greeting instead of the ordinary ring back tone. The prospect of CRBT in China is quite good, and users can apply for services through IVR. After making a call, just follow the voice prompts to perform relevant operations.

The operator also offers to apply for the opening of the ring tone service through SMS and Web. After the user applies for and customizes the ring tone, the system will notify the customer of the application and customization information through SMS. Users can even upload their favorite music songs or recordings through the Internet. As your own personalized ringtone.

After activating the service, users can then set up their own ringtones accordingly to make it more personalized. Customers who subscribe to the mobile ring back tone service can customize the ring back tone in groups according to the calling number and dialing time. If no special settings are made, the calling customer will hear the default ring back tone. When the called mobile phone is turned off, not in the service area, or the client is busy, etc., what the calling client hears is still the usual voice prompt. After the user opens the ring back tone service, he can also control the opening or closing of playing personalized ring back tones, and can also download and change the ring back tones at any time.

However, with the development of this service, there is also a caller's demand for this service: some callers do not want to hear the ring tone of the called party due to reasons such as personal preference, experience, religion, and the situation when making a call. .
